Given numbers are 500, 478, 390, 778

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(500, 478) = 119500

GCD(500, 478) = ( 500 x 478 ) / 119500

= 500 / 478

= 500

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

So, Greatest Common Divisor of 500, 478, 390, 778 is 2
